Crosstalk may be a significant source of noise in wireline communication systems, especially those based on Digital Subscriber Line (DSL) technology. In International Telecommunication Union (ITU) standard G.993.5-2010 (i.e., G.vector), crosstalk may be mitigated by aligning or synchronizing transmissions from a given DSL access multiplexer (DSLAM) (i.e., intra-DSLAM crosstalk). However, crosstalk among different DSLAMs (i.e., inter-DSLAM crosstalk) may not be addressed by the G.vector standard. Therefore, inter-DSLAM crosstalk may be a significant source of noise in wireline systems, especially those based on the G.vector standard.
